Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
The electrolysis of water is a chemical change because it breaks down water molecules into hydrogen and oxygen gas. On the other hand, sodium chloride exposed to sunlight is a physical change as it may undergo phase changes, but the chemical composition remains the same.
Is dissolving sodium carbonate a chemical change?
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
What is the chemical equation of the reaction of litmus paper to sodium chloride?
Litmus paper is a mixture of dyes that change color depending on the acidity or alkalinity of a solution. When exposed to sodium chloride, which is a neutral salt, litmus paper does not undergo a chemical reaction. It remains unchanged in the presence of sodium chloride.
Can sodium be decomposed by a chemical change?
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
Is adding sodium to water a chemical change?
Yea it is a chemical change. The Sodium reacts with water in a chemical reaction in which the sodium displaces the hydrogen in the water, creating sodium oxide and hydrogen gas. The heat from the reaction ignites the hydrogen, which creates the explosion.

Is sodium a physical or chemical change?
Sodium is a chemical element, not a change.
What are examples of solids in a chemical change?
Examples of solids in a chemical change include baking soda (sodium bicarbonate) turning into carbon dioxide gas and solid copper turning into copper sulfate solution when reacting with sulfuric acid.
Is sodium and chlorine a physical change or a chemical change?
chemical
What is the chemical change of water?
The chemical reaction of water with sodium is a chemical change.
Is dissolving sodium carbonate a chemical change?
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
Why sodium carbonate is not a chemical change?
Sodium carbonate is a compound. Until you react it with something, it cant have or be a chemical change.

Litmus paper is a mixture of dyes that change color depending on the acidity or alkalinity of a solution. When exposed to sodium chloride, which is a neutral salt, litmus paper does not undergo a chemical reaction. It remains unchanged in the presence of sodium chloride.
Is the change between sodium and chlorine a physical change or chemical?
chemical
Is sodium can react with water a chemical change?
The reaction of sodium and water is considered to be a chemical change.
Can sodium be decomposed by a chemical change?
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
Is a physical change A. Forming a mixture B. Burning wood C. Food turning into waste in the intestines D. Turning solid sodium and chlorine gas into salt?
A physical change is A. Forming a mixture. Physical changes involve alterations in form or appearance without changing the chemical composition of the substances involved. In contrast, burning wood (B) and the chemical reaction that creates salt from sodium and chlorine gas (D) are chemical changes, while food turning into waste (C) involves both chemical and biological processes.
